Do you feel inconvenient to lock your device using the power button?

Are your afraid of wearing out the power button? (My n1 was repaired coz of that :< )

'Lock Screen App' is a tiny app that can help you lock easily (without power button).

Features :
•Lock device with one touch
(Same effect as pressing the power button)
•Not a widget so it does not run as service in the background
•Auto-kill itself after locking to save your Battery & Memory
•Tiny in size (<100k)

Features (Donation Version Only):
•Little bit faster
•Lock by long-pressing search button **not work on xpad/apad and device without search key**
•Get updates earlier

(You could find it using 'View more applications'/ the link in the app's settings page)

Thank you! :D


@@Compatibility Issues@@

1.New / Updated Moto devices may not be supported

Moto disallows lock screen in their OS updates, so it would not work on moto devices after updates and new device like Droid 3. I have reported it to moto, but they did not agree to fix!

2. For device running Android 4.X, sometimes flashing (screen on then off again) may happen, try to enable 'Force Lock' in Lock Screen Settings to fix it.

3.It has been tested to work on Galaxy Nexus and Android Simulators (2.2,2.3, 4.0.2, 4.0.4, 4.1, 4.2 & 4.3)
However, the dev cannot guarantee that it could run / uninstall on all devices [coz I don't have all the devices].

If you encounter problem with you device, feel free to drop me an email!

### How to uninstall? ###
Locking Screen in Android requires the user of device administration function, you must deactivate device administration *BEFORE* uninstall to avoid error!

To do this:
•Go to "Lock Screen Settings" (in launcher) -> "Remove Device Administrator"
~See screenshots~
Alternatively, you may do it via
•Go to Settings -> Location & security (or Security) -> Select device administrators -> Uncheck this app.

After that, uninstall it in Play Store, in case of error during uninstall in Play Store, do it at Settings->Apps->Lock Screen-->Uninstall

[To use other hardware keys to unlock your device, try 'Widget Locker' / 'No Lock' app (not developed by me)]

    Lightweight and does what it says. Needed for every Android device. Save a few clicks on that power button.

    Simple and lightweight. Perfect as a companion to Switchr (pin the app) so you don't need to go to your home screen to lock.
